The victim, Debbie Schultz, said she's relieved someone is going to be held responsible for the crash one week ago.

Schultz suffers from post traumatic stress disorder, and while her physical wounds are healing, she said her emotions are still raw over the loss of her service dog, Lexi, and the arrest of the driver, who was identified as Carlos Ward, 29.

A police officer in Waukesha spotted the Jeep on Thursday, and Ward was arrested.

"A piece of trim that was left behind on the original hit-and-run was able to match up perfectly on the vehicle, and we're even able to see, presumably, dog hair in the trim work of that vehicle," Waukesha Police Department Capt. Ron Oremus said.

In a phone interview, Ward said he didn't stop because he was scared and nervous.

"It was something that, in the shock of the moment, I panicked and whatever," Ward said. "I understand how she feels about her dog, and I apologize for harming her dog. I'm cooperating and making sure that everything is getting taken care of."

Schultz said she's not buying Ward's explanation that he didn't know he had struck the dog.
